The trolley body 31 is provided with a material cavity 311, and a material outlet 312 is formed at the hollow bottom of the material cavity 311. The material cavity 311 and the material outlet 312 are conventional structures. The core invention point of the present application lies in the design of the drawing plate 32, the drawing plate 32 is movably mounted on the trolley body 31, the drawing plate 32 is driven by the drawing plate driving unit 33 to perform a drawing action for adjusting the opening degree of the discharge port 312, that is, the drawing plate driving unit 33 drives the drawing plate 32 to move, so as to flexibly adjust the opening degree of the discharge port 312. The two limit states of the opening adjustment of the discharge port 312 are a fully closed state and a fully opened state of the discharge port 312, respectively.

The trolley body 31 is provided with a reference direction, the cloth direction is from back to front, the drawing plate 32 is arranged behind the discharge port 312, the drawing direction is from front to back, the cloth is in an initial state, and the drawing plate 32 moves forwards to completely close the discharge port 312; in the material distribution process, the opening of the material outlet 312 is adjusted by taking the front end of the material outlet 312 as an opening end. By the design, the material distribution direction of the trolley is consistent with the opening adjustment direction, and the material distribution effect is effectively controlled. Of course, the design of the draw plate 32 is not limited to this orientation definition.

In the embodiment, the pulling plate driving unit 33 takes the form of a cylinder. In order to facilitate the matching installation of the drawing board driving unit 33 and the drawing board 32, the drawing board driving unit 33 and the drawing board 32 are transitionally connected through a bearing board 331.

So, the present case cloth dolly 300 adopts and has the even cloth thinking that is totally inequality with the tradition, and the tradition design thinking is at the inside relevant refining subassembly that adds of dolly, and the refining mode of operation does, and after the base material was accomplished from the discharge gate unloading in the dolly, through the action of refining subassembly, will accomplish the inhomogeneous cloth phenomenon of unloading and do the refining and improve the processing. The design idea is originally created, the opening of the discharge port is adjusted by the drawing plate, and the operation mode of material refining is that the material refining is carried out in the discharging process of the discharge port; specifically, when the discharging port 312 discharges materials, the drawing plate 32 is controlled by the drawing plate driving unit 33 to perform reciprocating drawing action, so that a unique uniform material scattering mode controlled by the opening degree of the discharging port is obtained, and the discharging amount is controlled by controlling the opening degree of the discharging port 312, so that the effect of uniform material distribution is realized while the discharging is finished.

The drawing plate 32 performs reciprocating drawing action, which means that in the feeding process, the drawing plate 32 does not perform opening degree increasing action in one direction (backward), but performs opening degree reciprocating gradual changing action (with back reduction in the increasing trend) in the overall backward direction trend (with forward returning action in the middle), and the drawing action mode is comprehensively set according to the running speed of the trolley cloth, the total amount of the base material, the feeding characteristic of the base material, the size of the cavity of the receiving mold and the like.
